Abstract: A beam scanning apparatus for scanning light beam on a scanning surface, has a deflector, a scanning mechanism, a detector and a controller. The deflector deflects the light beam so as to guide it to the scanning surface. The scanning mechanism functions to change at least one of a deflection angle and a deflection position of the deflector so that the light beam is scanned on the scanning surface. The detector detects the scanning state of the light beam by the scanning mechanism on the scanning surface by receiving the light beam from the deflector. The controller corrects at least one of the deflection angle and the deflection position of the deflector on the basis of the detection result of the detector.

Abstract: Apparatus for controlling the combining of video signals includes a field rate microprocessor (10) that generates edge data defining the edges of a polygonal first picture (KP) which is to be keyed into a second picture (B) to produce a composite picture. Two line rate microprocessors (16, 18) generate from the edge data, for each horizontal scanning line of the composite picture in which a row of pixels corresponding to that scanning line is intersected by edges of the first picture, signals representing: the horizontal locations of first and second start pixels, namely those of the row of pixels in which first and second edges (e.g. E1, E2), respectively, of the first picture (KP) start to intersect the row; the gradients of the first and second edges; and a key value (the proportion of the first picture to be contained in a pixel of the composite picture) for each of the first and second start pixels. A key value generator (32) generates, for each scanning line of the composite picture, a key value for each successive one of the row of pixels corresponding thereto, by: ramping up the key value from zero, for pixels preceding the first start pixel, by incrementing the key value for the first start pixel, for pixels following the first start pixel, by an amount per pixel determined by the gradient of the first edge (e.g. E1), until the key value reaches unity; and ramping down the key value from unity, by decrementing the key value for the second start pixel, for pixels following the second start pixel, by an amount per pixel determined by the gradient of the second edge (e.g. E2), until the key value reaches zero.

Abstract: A testing method and apparatus for determining the reaction time of machine operators, especially drivers of automotive vehicles. A series of images are projected onto a viewing screen to be observed by a student at a student station. The images comprise one or more visual depictions of various operating conditions, including non-threatening and threatening conditions. After presenting a sequence of non-threatening conditions images, an "action cue image" representing a threatening condition is projected. The elapsed time between the projection of the action cue image and the initiation of the required response of the student is measured to derive the student's reaction time, in terms of seconds or distance traveled at a specified speed.

Abstract: A cooling apparatus for cooling a given device which is incorporated in a computer or similar electronic equipment (3) and generates heat by circulating a liquid coolant through the device (30) of interest. A secondary cooling liquid exchanges heat with a primary cooling liquid in a heat exchanger (13) and then flows into the device (30) of the equipment (3). When the difference in temperature between the secondary cooling liquid and the interior of the equipment (3) decreases beyond a predetermined value, a heat exchanging mechanism is caused to stop operating. On the increase of the difference in temperature beyond the predetermined value, the heat exchanging mechanism is caused to begin operating again. Alternatively, the operation of a secondary cooling liquid feeding mechanism may be interrupted and then set up again on the basis of the above-mentioned difference in temperature.

Abstract: A method for immunoassay of a trace vital component is provided. Using fine particles as label or marker 21, the fine particles are captured on reaction solid phase 10 in proportion to an amount of analyte by a specific reaction such as antigen-antibody reaction. Then, the fine particles are liberated and the number of fine particles is counted to determine the amount of analyte. The solution to be assayed containing the liberated matters is introduced into flow cell and pulse-like fluorescence emitted when the fine particles pass through a flux of laser light irradiated from the direction crossing the flow at the right angle is detected and the pulse is counted to count the number of fine particles 21. 
     The marker or label, i.e., the fine particles once captured on the reaction solid phase are liberated and then counted. Therefore, influence of the label non-specifically bound to the solid phase can be eliminated. By using the fine particles as the label and counting the number of the particles, detection having a high linearity can be realized even at a low concentration.

IPC: G06F9/38

Abstract: A high-performance CPU of the RISC (reduced instruction set) type employs a standardized, fixed instruction size, and permits only simplified memory access data width and addressing modes. The instruction set is limited to register-to-register operations and register load/store operations. Byte manipulation instructions, included to permit use of previously-established data structures, include the facility for doing in-register byte extract, insert and masking, along with non-aligned load and store instructions. The provision of load/locked and store/conditional instructions permits the implementation of atomic byte writes. By providing a conditional move instruction, many short branches can be eliminated altogether. A conditional move instruction tests a register and moves a second register to a third if the condition is met; this function can be substituted for short branches and thus maintain the sequentiality of the instruction stream. Performance can be speeded up by predicting the target of a branch and prefetching the new instruction based upon this prediction; a branch prediction rule is followed that requires all forward branches to be predicted not-taken and all backward branches (as is common for loops) to be predicted as taken. Another performance improvement makes use of unused bits in the standard-sized instruction to provide a hint of the expected target address for jump and jump to subroutine instructions or the like. The target can thus be prefetched before the actual address has been calculated and placed in a register. In addition, the unused displacement part of the jump instruction can contain a field to define the actual type of jump, i.e., jump, jump to subroutine, return from subroutine, and thus place a predicted target address in a stack to allow prefetching before the instruction has been executed. The processor can employ a variable memory page size, so that the entries in a translation buffer for implementing virtual addressing can be optimally used. A granularity hint is added to the page table entry to define the page size for this entry. An additional feature is the addition of a prefetch instruction which serves to move a block of data to a faster-access cache in the memory hierarchy before the data block is to be used.
